Geotechnical Property Modeling in Civil 3D and BIM integration

One of the most important and current activities through the world is the construction ones. In fact, infrastructure is a good way to meet the social and economic needs. In many countries the quality of life is connected to the infrastructure available. For this reason, construction has and still is a principal activity in the world. Having this in mind, a primary step for any project should be the soil exploration and excavation. Is a key factor to have proper geological and geotechnical information, that allows us to build the surface and subsurface information modeling, because it has a direct impact on the cost, time and construction hazards and subsequently in the project design. Today, the development of GEOBIM eases the analysis of the data, saving cost, speeding up processes and avoiding risks. The geographic and geotechnical data (GEO) are the ones that provides the information about the existing soil surfaces while building information modeling (BIM) gives the information about the asset in a great detail. However, the integration of GEO and BIM for soil surfaces modeling and classification is still being explored. The present project aims to present the integration of GEO and BIM for modeling geotechnical properties based on soil type. For the creation of the 3D soil surfaces, was choose the use of a commercial program (Civil 3D). For the correct interpretation of the soil surfaces was use the geotechnical analysis of the engineer and the help of the interpolation methods of the software Civil 3D. Kriging and the nearest neighbor inverse have been the interpolation methods used in this project for the generation of the soil surfaces. The method has been applied to the in-situ test data of the Parco della Salute, della Ricerca e dell´Innovazione, in the city of Turin. The result demonstrate that the proposed methods successfully integrates GEO and BIM providing a 3D surface model, that has excellent potential to provide information about soil type, depth, volume of each available soil layer, between other properties that can be used by the construction planners to identify and take the best options regard the project. In the other hand, also is important to considered that it is critical to the model how is manage the input data and the engineer criterion to discretize and build the correct asses information into a model.
